We were asked to create a workshop as part of an event to celebrate the Sensing Spaces exhibition, in which architects from around the world had filled the Royal Academy with monolithic stone, straw, wood and plastic edifices.

Three groups of school visitors were asked to use spoons to carve and chip away at four massive blocks of ice, slowly changing the form and clarity of the ice. The ice shavings went into cones and were drizzled with some syrups we made - hay, rhubarb, apple and douglas fir. Next we had all the kids hold a balloon filled with aromas of birch and hinomi woods, in response to the fragrances used in part of the exhibition. We released the balloons in a big noisy flurry, releasing the aromas into the air.
